[o al?, echo/m, it may concern:

" Be it known that I, PETER B. SAUGEN, a citizen of the United States, and resident oit the city of Tacoma, county of Pierce, State of Washington, have invented certain new and useful Improvements in Carbondeinoving devices, of which the following is a specification.

y v `My invention relates to improvements in carbon removing devices; more particularly to devices `oli that character ier removing carbon deposits ironi the walls et cylinders of internal combustion engines.

It is the principal object of the invention to provide a device of the above stated char acter that is adapted i'or use in cylinders of `various diameters, which can be easily applied and operated and whereby all carbon deposits can be quickly and thoroughly reM moved from the cylinder walls and troni ytheends of pistons operating in said cyln inders i It is another object ofthe vinvention to picivide a carbon reinoving device conipris- `ing a rotatableblocli: wherein a plurality oit scraping blades are yieldingly mounted for radial movementand which may, by pressure applied against the block, be actuated toengage the cylinder walls to clean them ot carbon as the block is rotated.

`A-iiother object of the .invention resides in the detail construetionfof the block, the

i character of the blades used and the manner in which they areniounted.

` In accomplishing these and other objects oil' the invention, I` have provided the iinproved details of construction, the preferred forms of which are illustrated in the accoinpanying drawings, `wherein-- `Figure Il isa `perspective view illustratingtlie 4application of a carbon removing device embodying the present invention `within the cylinder of an engine; also show'- `ing the application of one type of actuating line 4;'4 in Fig. 3.

Fig. 5 is a horizontal sectional view taken on the line 55 in Fig. 4;

Relerringinore in detail to the several views of the drawings, wherein like refer- Specication of Letters fiatent.

Application filed November 29, 1920.` Serial No. 426,896.

ence numerals designate the saine or lilio pi ts-- i y l des gnates a blade supporting block, or head, wnich is preferably but not necessarily of a triangular torn?. as is shown in Fig. 3, and which is provided centrally on its upper .iface with a wrench head Q; whereto a wrench er other seclreted tool, as shown at 3 in Fis. i, may be applied in such inanner that through it pressure inay he applied to the bloeli while it is being rotated.

Formed within the blocli, in planes per ijienrflicillar to its top surface and radially with respect to a central vertical line, are" slots 5, and slidably contained within these slots are Jing` blades 6 fprovided along their outer vertical edges with 'larly beveled scrapi surfaces 2' and along their lower edges with beveled scraping surfaces Si; th@ edges 8 all lying normally in the saine horizontal plane.

The liaise l() ci= the walls ol" each of the slots 5 iforined on an incline of about 2l-5 degrees, is shown best in Fig. el, and :rtends ein the edge et the blocli at its p Atace to apprfniiinately the middle oi'f the blocli at the lower surface. rlllhe inner corner olf each of they scraping blades likewise beveled to engage the inclined buses oil?. their respective slots in such nianner that, with the lower edges oil. the blades seated a inist a suyjiporting ineinber such as the il )per end oit a piston, downward movement e'll'ected by pressure on. the hloeli will cause the blades to benioved radially outward and into engagement with the cylinder walls.

ln order that the blades may he held. in position and iiorinally retained at their inner liniijt oittravel, l have provided each with `an opeiiiiil wherein collars, or sleeves 'l5 portions of the blocli l have formed pockets l5 flor receiving the spring band and collars within the blades, so that these parts may he within the limits the block and will in. no`

way interfere with. its operation.

Assuming that the different parts are so constructed and assembled, the device would beused inthe following manner: For reas shown at 3, to cause the blades to beactuated outwardly against. the cylinder walls,

and simultaneously the block is rotated to4 cause the blade edges 7 to scrape the carbon deposits therefrom, and the edges 8 to clean the piston end. Removal of pressure from against the block permits the spring band to retract the blades within the block so that the `devicemay be removed from the cylinder.

lt is apparent'that a device-of the above character may be applied to cylinders of varieus diameters, and that beingk equipped with beth horizontal and vertical scraping edges, the cylinder walls and piston ends will be, simultaneously cleaned. n

lt is` further apparent that such a device will be very effective, easily operated, will quickly and thoroughly perform its work and can bemade at a relatively small cost. yHaving thus described my invention, what l claim as new therein and desire to secure byfLetters-Patent isl. A device of .the character described comprising'a body block having means thereon fer connection with an actuating tool, a plurality of blades slidably mounted in the block and having scraping surfaces at their outsideand lower edges which are adapted, when the devicel is in use, to respectively scrape the inside wall and base of a cylinder, said blades being mounted within the block in such manner that Vpressure against the block which would tend to force it toward the base ot the cylinder, will eliect radially expanding pressure against the blades.

2. A carbon removing device of the character described comprising a body block having aV plurality of radially directed slots therein, blades slidably Vmounted within the said slots and having their outer and lower edges beveled to form scraping surfaces; said lower edges being adapted to lie normally within the same plane and the said outer edges being perpendicular to said plane, means for eiiecting radial movement of the blades by downward pressure on the block and means on the upper face ot the block whereby connection may be made with an actuating tool.

carbon removing device of the charactcr described comprising a body bleek having means thereon for connection with an actuating tool and having a plurality of radially directed, vertical slots formed therein; the bases et said slots being inclined inwardly and downwardly with respect to the vertical axis ot the bleek, scrapingl blades slidably contained within said slotsl provided with vertical and horizontal scraping edges lying respectively without the periphery and below the lower iace of the block and having their inner edges beveled to conform te the inclined bases or said slots and seated thereagainst, and yieldable Vmeans for normall retaining the blades rctracted within the slots of the block.

f-l. A carbon removing device ol. the character described comprising a bloclr having` a means thereon for connection with an actuating tool and having a plurality ot vertical, radially directed slots formed therein; the bases of said slots being inclined inwardly and downwardly to the center of the block A at its lower iace, scraping blades nounted slidably within said slots havingl vertical scraping edges extended beyond the periphery of the block and having horizontal scraping surfaces extending below the lower tree thereof and having their inner edges inclined in accordance with and seated against the bases of said slots, said blades also having apertures therein and a spring band extending about the bloot; and through said aperturesrto yieldingly resist outward movement of the blades.
